The description relates to passive two-phase immersion cooling of computers, such as servers. One example can include multiple liquid immersion tanks configured to contain servers immersed in a liquid-phase of a coolant having a boiling point below a maximum operating temperature of the servers such that operation of the servers generates heat that is transferred to the liquid phase of the coolant and causes a portion of the coolant to boil to a gas phase of the coolant. The example can include a single phase separator tank and a single heat exchanger coupled to the multiple liquid immersion tanks as a sealed cooling system and configured to receive the gas phase of the coolant and configured to transition the gas phase of the coolant back to the liquid phase of the coolant and to automatically deliver liquid phase of the coolant to an individual liquid immersion tank responsive to further boiling producing additional gas phase of the coolant that evacuates the individual liquid immersion tank.
